To all whom it may concern g Be it known that I, ALFRED FoRnaNoEn, asubject of theKing of Sweden, and resident of New York city, in thecounty and standard material and even scrap material as far aspracticable, and to give the lamp mounting a large variety of distinctfunctions, so as to increase the adaptability and general efliciency ofthe lamp.

Reference is made to the accompanying drawings forming a part of thisspecification, and in which like letters indicate like parts.

Figure 1 isa side elevation of the mounting complete. Fig. 2 is a planview of the spool and parts associated therewith, serving as a base. iFig. 3 isa detail view, showing the construction. of the eyeused forguiding the lamp cord, and as a pivotal support for the lamp socket.Fig- 4 is a cross section throughthe base. Fig.5 is a side elevation,showing the mounting as supported upon a wall by aid of a suction cap,forming a part of the device. Fig. 6 is a fragmentary side elevation,showing the lamp and parts associated therewith as supported upon aboard by spring pressure. Fig. 7 is a detail view, showing in crosssection the suction cap. Fig. 8 is a detail view, showing improved meansfor enabling the lamp socket tobe turned.

A pair of metallic spool members 9, 10, made substantially alike, areprovided, each of these parts being preferably stamped from a singlesheet of metal, which may or may not be scrap material. These spoolmembers are provided, respectively, with cup-like bottoms 11, 12, andare so proportioned that when these bottoms are placed together, asindicated in Fig. 4, the outer peripheral edges of the spool memberswill be spaced apart, thus forming a groove 13 which merges into anannular passage 14, the cross diameter of which is much greaterSpecification of Letters Patent.

than the width of the groove 13. The spool member 9 is provided with ahole 15. A

clamping disk 16 is provided with a hook 17 A clamping bolt 18 extendsthrough the clamping disk 16, and also through the bottoms 11, 12 of thespool members.

A supporting stem 19, made of a single piece of spring wire, is providedwith a portion 20 bent substantially into annular form, 111118 portlonbeing disposed between the clamping disk 16 and the bottom 11. The bolt18, by exerting pressure upon the clamping disk 16, causes this disk topress upon the annular portion 20 of the supporting .stem. The clampingdisk 16 is provided with a notch 16 through which the stem 19 extends asmay be understood from Fig. 2. The spring stem 19 is bent to form a con-Patented Jan. 18,1916.

volution 21, and is provided with a backwa rdly extending portion 22,the latter being provided with a convolution 23. The

portion 22 of the spring stem is further provided with a part 24integral with it, this part supporting a suction cap 26, which isprovided with a thick portion 25 through which the part 24 extends, andinto which it fits tightly.

A friction ring'26 is engaged externally by the convolution 21. A pieceof spring wire 28 is provided with a convolution 27 engaging thefriction ring 26 externally.

The piece of spring wire 28 is further provided with a portion 29integral with it and bent into annular form, so as to constitute aconvolution. This convolution fits into a groove 30 carried by a lampsocket 31,'so as .to support this lamp socket, as indicated in Fig. l. Alamp cord 32 extends into the lamp socket 31, in the usual or anydesired manner. Connected with this lamp cord is a cord socket 33 whichmay be fitted into an electrolier or other appropriate part from whichthe electric current is to be supplied.

The lamp cord32 carries a bead 34, which,

in-this instance, is made of soft rubber. The bead can be crowdedthrough the groove 13,

as indicated in Fig.1, and thus serves as a fastening for preventing thelamp cord piece 37 for turning the current on'and ofl'.'

An incandescent bulb 38 is detachably-connected with the socket 31, inthe usual or any;

desired manner as indicated, the various movable parts may be shifted inposition for different purposes. If the device is to be stored away orcarried in the pocket, the lamp cord 32 is wound around upon the spoolmember, as indicated in Fig. 1, the bead 34 being pressed through thegroove 13, and thus preventing the cord from becoming unwound. The bulb38 may be removed from the socket 31, and this socket bent down, uponthe friction ring 26 as a center, and thus brought into the positionindicated by dottedlines in Fig. 1. The portion 22 of the spring stem issprung into the position indicated in Fig. 1, the suction cap 26 beingturned, if desired, upon the part 24 as a center, and thus rested uponthe bolt 18 or upon the clamp-- ing disk 16. The device now occupies acomparatively small space. In order to mount the deviceupon the wall 35,the portion 22 of the'spring stem is sprung outwardly so as to clear thespool member 9, or in other words, is brought into its normal position.The suction cap 26 is next pressed against the wall 35, so that thespool is located directly below the suction cap. The socket 31 may 'nowbe bent upwardly or downwardly to any desired angle. If it be desired toturn the socket 31 a horizontal plane, the suction cap is detached fromthe wall and moved substantially to the same horizontal level as theaxis of the spool, and then screwed to'the wall by suction. The socket31 may be turned relatively to the convolution 29, which serves as abearing for supporting the same. The

. friction ring 26*, besides serving as a bear ing for the convolution27 answers likewise as an eye for guiding the lamp cord 32. When thedevice is to be mounted upon a board 36, as indicated in Fig. 6, thespool is placed upon one side of the board, and the portion 22 of thespring stem is sprung over to a point adjacent the opposite sidethereof, so that the portion 25' of the suction cap presses against theboard 36, at a point opposite the location Ofthe spool. The device isthusheld by spring pressure upon the board, and may be adjusted as abovedescribed. As the book 17 prevents rotation of the clamping disk 16, thespring stem 19 maintains always the sameposition relatively to thespoolwhen the'parts are assembled as indicated in Fig. 4. Y

he operation of my device is as follows: The parts being assembled andarranged" I do not limit .myself to the precise construction shown, asvariations may be made therein without departing from the spirit of myinvention, the scope of which is com- .mensurate with my claims.

' 'Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is as follows:
